How to keep physics fast-moving objects from going through the ground plane? (not python or game)
I solved my rigid body physics “falling through the floor plane” problem by raising: Scene > Rigid Body World > “Steps Per Second” and “Solver Iterations” above their default levels of 60 and 10. This scene has 10,000+ fast-moving cube objects. At default levels, over 100 objects fell through the floor plane. At 5 times the defaults, (300 and 50 respectively), only 3 objects fell through the floor. At 10 times the defaults (600 and 100), NOTHING fell through the floor. The calculation took longer, but was probably generally more accurate than with default Steps and Iterations levels.
